If you use Send To Kindle app, email is bypassed and the limit is 50MB. Plus you can make adjustments to Title/Author and control which (if any) devices get the document, whether or not to store in cloud. Almost no reason to use email unless Send To Kindle is not available.
It is trivial to split PDFs wherever it is logical to do so and get the size down (if you don't worry about breaking PDF links).
